Ethernet Radio Planning & Link Engineering

Course Overview:

Is microwave dead or outdated? The first commercial microwave radio point-to-point link was deployed back in 1950, however, the requirement to backhaul mobile radio traffic quickly and reliably, led to exponential growth of this industry before the turn of the century. It is often predicted that fiber optic transmission will stunt this growth. However, considering fiber is not available in the access network, microwave radio will continue to be the technology of choice for 4G Backhaul such as LTE.

New developments in microwave radio will also make it possible to support the IP-RAN by carrying Ethernet traffic over microwave more efficiently It also is a critical transmission medium for public service utilities, network service providers and government or military telecoms networks. Financial and practical restrictions mean that a mix of new and legacy systems working together and as bandwidth is limited, baseband and RF bandwidths must be optimised.

Despite the phenomenal growth of microwave radio, the system design methods are often outdated, with the design rules adapted from the old analogue systems without understanding the impact on deployment costs or performance degradation. With the increased restrictions on physical infrastructure such as towers, due to environmental concerns, radio links need to be made to work in non ideal situations and so practical, real-world guidance is provided to make a risk, cost assessment.

Course Objectives:

This course will bring you up to date on the latest standards and design methodologies that can significantly improve system performance with dramatic reductions in infrastructure costs. It will also dispel the many myths that dog the industry due to lack of understanding on some of the fundamentals of radio transmission.

Lastly, it will help you assess the risks and practicalities of alternative technologies, including unlicensed microwave, so that the appropriate technology is deployed for the appropriate application.
